  The objective was to evaluate the effect of grazing intensities over black oat+annual ryegrass biomass production and its residual biomass decomposition. The experiment was laid out as a randomized block design with four replications. Black oat+ryegrass grazing intensities were characterized by different pasture sward management, with the entrance of animal at pasture heights of 25, 30 and 35 cm and post-grazing herbage heights of 5, 10 and 15 cm. Litter bags technique was used to monitor the process of decomposition and the bags were left on the soil surface and collected after 15, 30, 60, 90, 120, 150, 180, 210, 240 and 270 days. The highest grazing intensity (25x05 cm) affected pasture production, showed the lowest amount of residual biomass after grazing and the highest rate of biomass decomposition. As the sward height increase to 30x10 and 35x15 cm, the rate of accumulation, forage production and total residual biomass after grazing increased and its decomposition rate decreased. Black oat+ryegrass pasture mixtures should not be management at height lower than 30x10 cm on rotational stocking because many variables that interfere on the sustainability of the crop-livestock system are adversely affected.
